The four fields on your invoice that determine whether you get paid this month or next quarter. Real language, real due dates, and one late-fee clause that actually works.
A contractor with 60-day average receivables is banking the difference for customers. Four fields on the invoice that move payment speed: 1) Explicit due date (not "Net 30"), 2) Payment methods in order of preference (card first, ACH second, check third), 3) Late-fee clause of 1.5%/month plus $25 flat fee, 4) Named contact with cell and email. Real footer language: "Payment due [date]. Pay by card or ACH from the button above, or send a check to [address]. Balances unpaid after the due date accrue a $25 late fee plus 1.5% per month. Questions? Text [cell]." Don't use legal boilerplate, don't say "terms attached separately", don't leave vague pay-to labels. Chase cadence: day 1 text, day 7 email, day 14 phone, day 21 collections letter. FieldKrew automates the reminders.
